[slackware-security]  m4 (SSA:2008-098-01)

New m4 packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, 10.2,
11.0, 12.0, and -current to fix security issues.

More details about the issues may be found in the Common
Vulnerabilities and Exposures (CVE) database:

Here are the details from the Slackware 12.0 ChangeLog:
patches/packages/m4-1.4.11-i486-1_slack12.0.tgz:  Upgraded to m4-1.4.11.
  In addition to bugfixes and enhancements, this version of m4 also fixes two
  issues with possible security implications.  A minor security fix with the
  use of "maketemp" and "mkstemp" -- these are now quoted to prevent the
  (rather unlikely) possibility that an unquoted string could match an
  existing macro causing operations to be done on the wrong file.  Also,
  a problem with the '-F' option (introduced with version 1.4) could cause a
  core dump or possibly (with certain file names) the execution of arbitrary
  code.  For more information on these issues, see:
  (* Security fix *)

Where to find the new packages:

HINT:  Getting slow download speeds from
Give a try.  This is another primary FTP site
for Slackware that can be considerably faster than downloading
directly from

Thanks to the friendly folks at the OSU Open Source Lab
( for donating additional FTP and rsync hosting
to the Slackware project!  :-)
